The PPA also adjusts the expected capacity of the project to approximately 26MW, revises the purchase price per megawatt, and extends the term of the agreement from 20 to 25 years.

The Geysers geothermal field is the largest producer of geothermal electricity in the world and presently generates about 900MW of clean, base load electricity, the company said.

Western GeoPower (WGP) is a subsidiary of Ram Power, a US- based renewable energy company.

NCPA general manager James H. Pope said NCPA has a longstanding commitment to clean, renewable geothermal energy from the Geysers and we are very pleased with the agreement with Ram Power.

Ram Power Interim President and CEO Walt Higgins said the company remains vigilant in executing the business plan for the Geysers project and we are very pleased to have NCPA partner with the company in delivering clean, reliable geothermal power to Northern California.
